FLY-SCREEN.

Specification of Letters Patent.

Patented July 23,1907.

Application filed December 3, 1906. Serial No. 346.966.

To all whom 'it may concern:

Be it known that I, THOMAS NORUM, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Fly-Screens, of which the following is a specification.

This invention appertains to means for protecting verandas, porches, and similar exposed places so as to keep off flies, mosquitoes, and like'winged insects.

This invention provides a screen of novel structure and formed of sections which are adapted to be easily handled and quickly placed in position and adapted to be easily removed and stowed away in a small space, thereby enabling the screen to be quickly placed in position during warm weather and laid aside during the cold season when exposed places, such as porches, are not infested by flies and like insects.

The invention contemplates a novelstructure of frame and means whereby the screen material, or wire fabric, may be conveniently and expeditiously attached thereto, or removed as may be required.

The invention further provides peculiar securing means cooperating with the screen frame, whereby the latter may be attached to the frame-work of the porch, or like place, to be protected, and whereby positive connection is had between the screen frame and the supporting structure, so as to preclude displacement by Wind, or ordinary knocks.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and accompanying drawings. I

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

Figure 1 is a detail view of the invention showing the same applied. Fig. 2 is a horizontal section on the line xx of Fig. 1. Fig. 3 is a detail perspective view of a portion of the screen frame showing the parts on a larger scale. Fig. 4 is a detail perspective view showing the means for connecting a door jamb to the floor, or like support. Fig. 5 is a detail view of a modified form of stay. Fig. 6 is a horizontal section on the line y y of Fig. 5. Fig. 7 is an enlarged transverse sectional view through one of the stays.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The screen. comprises frame bars, screen material, such as ordinary wire fabric, and stays between the frame bars and the sections comprising the screen to stiffen and brace the latter and to overlap and secure the joints formed between the screen fabric. The

frame bars are adapted to occupy a position at the upper and lower edges of the screen, although they may be arranged in any position found most advantageous in adapting the invention to a particular location, or structure to be protected. Each frame bar comprises a strip 1 and a clamp 2, said parts being of substantially the same length. The strip 1 is grooved in its outer edge, as at 3, to receive heads, or projecting parts of the fastenings employed for attaching the screen to the parts of the structure to which the screen may be fitted. A rabbet 4 is provided in a side of the strip 1 adjacent to its inner edge and receives the clamp 2, the shoulder 5 formed at the inner edge of the rabbet, being under cut to overlap the beveled edge 6 of the clamp 2. The clamp 2 consists of a strip which in cross section corresponds to the outline of the rabbet 4 so that when the parts are assembled and the clamp is in proper position, its outer side and edge come about flush with the side and edge of the strip 1. The screen 7 which may be of any material, preferably wire fabric, has an edge portion secured between the strip 1 and clamp 2 and is held in place by means of tacks 8 which are driven into the rabbeted portion 4 of the strip 1 a distance so as to provide a space between their heads and the face of the rabbeted part 4, corresponding to the thickness of the screen, the heads of the tacks being of a size to pass through the meshes of the screen and engage therewith after the fashion of a button and button-hole fastening. A groove 9 is formed in the inner face of the clamp 2 to receive the heads of the tacks 8 and admit of the screen being clamped between the members 1 and 2. Screws, or fastenings 10 secure the clamp 2 to the strip 1. It will be understood that the strain upon the screen is sustained by the tacks 8, the clamp 2 serving to prevent the screen becoming accidentally disengaged from said tacks, and also serving in a measure to grip the screen and thereby supplement the action of the tacks 8.

It will beunderstood that the screen may be of any length but for convenience of handling, it is made up of sections.

For stiffening and strengthening the screen, stays are located at intervals in the length thereof, each of the stays comprising companion strips 11 between which the screen is clamped, and secured, screws, or fastenings 12, connecting the pairs of strips on opposite sides of the screen. The stays fit snugly between the frame bars, their ends abutting against the inner edges thereof. It will thus be understood that the stays in addition to stiffening and strengthening the screen frame,

where their meeting portions are jointed. as by means of a tongue and groove/as indicated most clearly at- 13inFig.2. I a

Where the screen is provided with a door opening, the jamb l4, bordering upon theopening is constructedv in substantially the same manner as a frame bar; the only .difierence: being that the same is made wider, =01 heavier. The end of the jamb. 14..is provided with headed fastenings by means tached to the structure to whichthescreen isifitted. Each clip 16 is of substantially U form in cross section so asto embrace opposite sides of the jamb 14 and one or more slots 17 are formed in a side of the. clip to receive headed fasteners 18 applied to a side. of the jamb.

It is preferred to secure molding, or like strip's'19 to the ceiling and floor of the porch, or veranda, or like place to be screened and to have the screen fit between saidmoldings, or strips, as indicated most clearly in Fig. l. The provision of the molding is not essential to the eificiency of the screen and the same maybe dispensed with, in which case, the screen will be secured directly to the ceiling and floor.

The clips 20 applied. tothe frame, bars of the screen are of, peculiar formation, each consisting of angularly di osed members 21 and 22, and lips, .or flanges 23 and 24 at the ends of the respectivemembers21.and 22. The member21 extends along aside. of the frame bar and its. lip 23 engages the inner edge of the clamp strip 2. The member 22 extends over the edge of the frame bar and its 1ip,. or flange 24, engages with the side of the bar opposite tothat adjacent to the sidemember 21. Each member ofthe clip is formed with a keyhole slot 25 adapted to receive headed fastenings,. or screws. The key-hole slot. in the member 22 is in line with the groove 3. of the strip-1 to admit of. the'head of the fastening cooperating withthe clip enterin the groove 3 so that a close fit may be had between the framev bar and .the part 'to which saidframe bar is attached. .By reason of the peculiar formation of the c1ips20, theymay be placed in position upon the frame bars of the screenwith the greatest ease and despatch and likewise readily removed therefrom when required for any purpose. .It is to be understood that the clips areplaced. inpositioni by having-theheads of the fastenings passed, through the enlarged, portions of the key-hole slots after which said clips. are movedto causethe headsof .the fastenings tooverlap the contracted, portions, of: the slots. j

In the modification as shown in Figs. 5 and .d, it, is, contemplatedto have the screen terminate about in line with the upper and lower. frame bars; vhencewhen the sectionsareplaced: together, the screen of each, in-, stead. of overlapping, willabut or come close together. To,providea. close joint,,thes.tay is of a width to. overlap contiguous end portions of thescreen and one member of the stay. is providedwith two rows of. headed fas-; tenings 26, similar. to the headed fastenings 8 andhave a like purpose, viz: topass throughmeshes near edges of which clips 16 are at-i,

of adjacent sections. The companion member of the stay is provided with two grooves 27 corresponding to the'rows'ofheaded'fastenings 26 to receive the same,

the screen being clamped between the members of the stay.

" For connecting the members of the stay, screw eyes '28'are-provided and are let into one member and are adapted to. have their eye ends pass through slots 29 of vtheemember having the grooves 27, said screw eyes being given a one-quarter turnto cause. their eye ends to sit crosswise of theslots 29 and hold the members of the stays together.
